Zhejiang University Research Team Developed Hexagon "Invisibility Cloak"

In October 31st, Professor Chen Hongsheng, a research team at Zhejiang University, demonstrated the effectiveness of a stealth device. When a pencil is placed in the device, the middle part of the pencil is missing, but the background pattern of the pencil is still visible.

Create perfect invisibility. Camouflage clothes "Scientists, engineers and technological enthusiasts have long dreamed of it." Professor Chen Hongsheng and other leading research teams in Zhejiang University are engaged in the electromagnetic wave stealth mechanism and experimental research. They believe that although the current technology has some limitations, Electromagnetic wave stealth It will be a great opportunity for stealth technology to enter the life field.

When an electromagnetic wave (including light wave) is irradiated to an object, it scatters on the object. When the scattered electromagnetic wave is received, it indicates that there is an object there. If we can make the electromagnetic wave "turn around" and walk around the object, the object can be "stealthy". The research carried out by the Chen Hongsheng team is based on this concept.

The team has proposed a design method of polygon "invisibility cloak" in visible light band, which can theoretically achieve stealth effect in all directions. In experiment, they developed a hexagonal cylindrical "stealth garment", whose working band can reach the whole optical band. In addition, the team also made microwave segment stealth devices.

The research carried out by Chen Hongsheng team not only promotes the invisibility garment from theory to practicality, but also effectively reduces the complexity of its implementation.

In October 31st, Professor Chen Hongsheng of Zhejiang University studied team members and doctor Zheng Bin finishing a "stealth" device.

In October 31st, Zhejiang University professor Chen Hongsheng research team The staff demonstrated the "stealth" device. A beam of light "turns" in the device, but it continues to follow the original direction after passing through the device.
